Instantaneous Power Theory and Applications to Power Conditioning

Angebote / Angebote:

This book covers instantaneous power theory as well as the importance of design of shunt, series, and combined shunt-series active power filters and hybrid passive-active power filters This new edition, written by a team of experts in the field, is fully updated with information on the latest electric power technology. The instantaneous power theory, or "the p-q theory, " makes clear the physical meaning of what instantaneous real and imaginary power is in a three-phase circuit. Moreover, it provides insight into how energy flows from a source to a load, or circulates between phases, in a three-phase circuit. This theory can be used in the design and understanding of FACTS (Flexible AC Transmission System) compensators. The book introduces many concepts in the field of active filtering that are unique to this edition. It provides a study tool for final year undergraduate students, graduate students and engineers dealing with harmonic pollution problems, reactive power compensation or power quality in general. In addition, the book: * Illustrates pioneering applications of the p-q theory to power conditioning, which highlights distinct differences from conventional theories * Explores p-q-r theory to give a new method of analyzing the different powers in a three-phase circuit * Provides exercises at the end of the chapters that are unique to the second edition
